Yet countless plant compounds, potentially with medical uses, still remain to be identified. Kazuki Saito, Ryo Nakabayashi and colleagues from the RIKEN Plant Science Center have now developed a technique for rapidly cataloging subsets of compounds in plant extracts based on mass spectrometry data as a first step toward a fully automated system for cataloging novel plant compounds.http://phys.org/news286184085.html
ChemistryFri, 26 Apr 2013 08:38:20 EDTnews286184085Sulfur in every pore: Improved batteries with carbon nanoparticlesFrom smartphones to e-bikes, the number of mobile electronic devices is steadily growing around the world. As a result, there is an increased need for batteries that are small and light, yet powerful. As the potential for the further improvement of lithium-ion batteries is nearly exhausted, experts are now turning to a new and promising power storage device: lithium-sulfur batteries. http://phys.org/news253279770.html
NanotechnologyTue, 10 Apr 2012 12:29:49 EDTnews253279770How the N2O greenhouse gas is decomposedNitrous oxide (N2O) is a harmful climate gas. Its effect as a greenhouse gas is 300 times stronger than that of carbon dioxide. Nitrous oxide destroys the ozone layer. In industrial agriculture, it is generated on excessively fertilized fields when microorganisms decompose nitrate fertilizers. Decomposition of nitrous oxide frequently is incomplete and strongly depends on environmental conditions. Researchers from Freiburg, Constance, and KIT have now identified the structure of the enzyme that decomposes nitrous oxide and the decomposition mechanism. Their results are published in the Nature journal.http://phys.org/news233226187.html

This is the new finding of a team of biologists that includes Joris Messens of VIB, a life sciences research institute in Flanders, Belgium, connected to the Vrije Universiteit Brussel. The scientists made this discovery by modifying the DNA of the intestinal bacterium Escherichia coli.http://phys.org/news177944623.html

Designed by Northwestern University chemists, it can remove mercury from polluted water, easily separate hydrogen from other gases and, perhaps most impressive of all, is a more effective catalyst than the one currently used to pull sulfur out of crude oil.http://phys.org/news161787550.html
